Yet another crazy week of college basketball continued to produce jaw-dropping moments Saturday. This most recent one happened in Madison, Wis.

There, coach Bo Ryan's Badgers sent their game with third-ranked Michigan to overtime with a buzzer-beating 3-pointer by Ben Brust from just inside the half-court line. The Badgers won it in OT when Trey Burke's 3-pointer went in and out for the Wolverines.

That loss for the No. 3 Wolverines means that, since the polls were released Monday afternoon, the Nos. 1, 2, 3 and 5 teams all lost road games.

That, obviously, paves the way for No. 4 Duke to take the No. 1 spot, if the Blue Devils can win Sunday at Boston College. Duke was No. 1 for four weeks earlier this season before losing to NC State on Jan. 12. A quick recap of this week's top-of-the-polls madness ...

— No. 1 Indiana lost at Illinois on Thursday, when Illini junior Tyler Griffey somehow slipped unnoticed under the basket with 0.9 seconds left and made the winning layup. Illinois had lost six of its previous seven games and was just 1-4 at home in Big Ten play before upending the Hoosiers.

— No. 2 Florida lost at Arkansas on Tuesday, when the Razorbacks played their best game in two seasons for coach Mike Anderson. Arkansas led by 17 at halftime and pushed its advantage up to 27 points in the second half before Florida rallied to make the final margin just 11 deceptive points. There never was a time in the second half Arkansas was in danger of losing.

— No. 5 Kansas lost at TCU on Wednesday in one of the more stunning games of the season. Unlike Arkansas, the Horned Frogs didn't win because of an amazing shooting display; at best, they were mediocre: 42.4 percent on 2-point attempts, 30.8 on 3-point attempts and an ugly 57.9 percent from the free-throw line. But Kansas was beyond awful on offense; after the game, coach Bill Self gave reporters this gem of a quote: "It was the worst team Kansas has ever put on the floor, since Dr. (James) Naismith was there."

After those games, maybe Duke shouldn't celebrate any new rankings quite yet. After all, the Eagles are pretty tough at home—they narrowly missed upsetting Miami and N.C. State earlier this season—and the Blue Devils are just 2-2 on the road in the ACC this season.
